Your lever is applying force to the approximate center of the board. It's not perfectly in the center and I suspect that the contact is such that the board ejects not quite vertically, but enough to be other than your desired trajectory.
It would be necessary to remove the bulk of the ejection block, leaving the portion nearest the lever. Alternatively, the ...
In this case its because they are emulating a bar mechanisms. This makes it possible for the designer to think of the problem in terms of revolute joints which allows them to use age old design principles with parallelograms and all.
Image 1: Equivalent bar mechanism
In this case the bar is rigid so the equivalent compilant needs to be rigid too. Doing it ...
I'll start from the particular example you are asking about. It is a positional adjustment device. It is heavily used in laser optical tables to provide micrometer adjustments. And it falls in the category of compliant mechanisms like you suggest.
There are a few requirements for these devices (most have been already pointed by others). IMHO, the main two ...
This looks like a wire edm part for those fine interior features. My guess is the design on the thin cuts was optimized for that process - i.e. constant width cut except at the entry holes, which are drilled.
Where the "thicker" hexagon-ish zone is, it is essentially not flexible. Essentially all the flexibility comes from where the sections ...
It is called a "fuse" connection, sometimes called the "fuse block", "fuse plug" depending on the trade.
Essentially it is simply a weakened link/connection between two components or a necking area in a location within an element, which is often seen in the tension test, so the failure can be triggered and limited to the ...
What you want is called the belt's neutral axis. The neutral axis is what coincides with the pulley's pitch circle. You have to look this up for each belt, because it depends on the way the belt is made.
But if this is a synchronous belt and pulley system, you are doing things backwards. The pulley profile is the established standard, and the belt guys have ...
My advice is to change the design if possible from vertical split to horizontal. i.e.
Not so good
The reason is that :
in the vertical solution the internal pressure will tend to separate the halves

you could go for a design that is ...
For a static joint, there are basically three options:
Use an adhesive of some sort to overcome irregularities in the mating surfaces.
Use a gasket to overcome irregularities in the mating surfaces.
Use sufficient clamping force to overcome irregularities in the mating surfaces.
For a purely 3D-printed object, option (3) is out: you can't get sufficient ...
This has been a feature since 2019 http://help.solidworks.com/2019/english/solidworks/sldworks/c_3d_textures.htm
The only 'downside' is that the output is a mesh body not BREP, but this isn't an issue in its intended use case of 3D print files. For rendering you would just bump map the smooth surface.
For traditional parts you still need some thickness for subtractive manufacturing processes to prevent the piece from deflecting too much during material removal to get repeatable parts.
The time it takes to remove additional material costs money, if less
material can be removed the part can be made for cheaper.
Usually you still want some rigidity at ...
If you've done any 3d printing you must have noticed that the material gets deposited in very thin lines.
The end result if you look at it in detail is the following:
The two big differences with an injection molding machine are:
temperature at exit
adhesion between layers.
In the case of injection molding machine, the material get injected all at once ...
